This case confronts us with fundamental problem, because it is interesting to see that finger length assessment in this case presents a contradiction regarding the methods that can be used to assess finger leng - through palm length and palm width:

- finger length to palm width is above the 97th percentile => indicative for extraordinary long fingers- finger length to palm length is just below the 25th percentile => indicative for short fingers- AVERAGE of finger length to palm width & palm length combined is above the 97th percentile => indicative for extraordinary long fingers

So, in case 1 we find in 2 out of 3 perspectives the assessment 'extraordinary long fingers', which is a clear indication that finger length in this example can 'safely' be described to be extraordinary long!

Case 2: excessive wide hand width!

This extraordinary case 2 hand represents a case of 'brachydactyly' (extraordinary short fingers) in Fragile-x syndrome:http://www.handresearch.com/diagnostics/simian-line-fragile-x-syndrome-case-2.htm

Case 2 confronts us with the same problem:

- finger length to palm width is below the 3rd percentile => indicative for extraordinary short fingers- finger length to palm length is just above normal => indicative for ordinary/slightly long fingers- AVERAGE of finger length to palm with & palm length combined is below the 3rd percentile => indicative for extraordinary short fingers

So, in case 2 we find in 2 out of 3 perspectives the assessment 'extraordinary short fingers', which is a clear indication that finger length in this example can 'safely' be described to be extraordinary short!

Conclusion:

Both in case 1 and case 2 the FL/PL approach does not appear to work at all, because it's results can be described to present an incorrect delusive assessment result!!!

Fair point?

PS. Finally, I would like to add that I am not sure that it is possible to present likewise cases regarding the FL/PB perspective... but I will report them as soon as I find such cases!

Another hand shape type that approaches to represent another type of an 'extraordinary hand shape' concerns the hypothetical hand shape example that presents ultimate balance - see the hand presented inside the picture above!

The details for this 'ultimately proportioned hand' (which concerns an example of excessive short hand length) are:

However. the details show that it would not qualify like the first two examples did in the previous post... since there is no obvious 'inconsistency' in any of the finger length perspectives for this 'ultimately proportioned hand'; which sort of illustrates how extraordinary and rare the 2 cases presented inside the first post really are!
